How do I chordify songs from Deezer?

To chordify a song from Deezer, first go to Deezer, play the song you're interested in, and click the "share" button on the top right of the player control dialog. A window will popup with a direct link to the song, like this one:http://www.deezer.com/track/75812870

You can then paste that link in the main Chordify window, just like any other YouTube or Soundcloud link.
